' NON-REFILLABLE BOTTLE.

To aZZ whom it may concern.-

' Be it known that I, J OSEPI-I BURKE, a citizen of the United States,residing at Victoria, in the county of Victoria and State of Texas, haveinvented certain new and useful Improvements in Non Refillable Bottles,of which the following is a specification.

This invention relates to non-refillable bottles, and more particularlyto that type which comprises a peculiarly constructed valve mechanismlocated in the neck thereof.

It has for its object to produce a device of this character which willeffectively prevent anything from being forced into the bottle after theinitial filling thereof and which is at the same time so simple anddurable in construction as to render its general adoption a practicalquestion.

For a full description of the invention and the merits thereof and alsoto acquire aknowl edge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand accompanying drawings, in Which Figure 1 is a vertical longitudinalsectional view showing the bottle in an upright position with the valveseated. Fig. 2 is a similar view showing the bottle in an invertedposition. Fig. 3 is a perspective view of the valve.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The numeral 1 designates the neck of the bottle, which is provided witha contracted portion 2 to form a valve-seat for the valve 3, and anannular groove 4 is also located within the neck of the bottleimmediately above the contracted portion 2. The valve 3 comprises a diskwhich operates within the groove 4 and is provided around the edge ofits upper face with a series of spaced projections or lugs 5, whichengage with the upper side of said groove 4. It will be discovered thatthe contracted portion 2 has its upper side curved downward to form aconcave surface and that the valve 3 is formed with acorrespondingconvex surface on its lower side, owing to a depression therein. A'stem6 is attached to the valve 3 and operates in the opening formed by thecontracted portion 2. This serves to prevent the valve from tilting orbeing shaken out of operative position. Owing to its peculiarconstruction, it will be seen that this valve will be very effective inSpecification of Letters Patent.

in the neck thereof to serve, respectively, as I an exit for the liquidand as an inlet for air. These openings may be sealed in any suitablemanner, as by corks 9.

In operation the valve is normally seated, as seen in Fig. 1, when thebottle is in an upright position, and hence prevents any substance frombeing forced in, as has been heretofore described. When the bottle isinverted, the valve falls back until the lugs 6 engage the top of thegroove 4. Theliquid then flows around the valve between the spaced lugs6 and out of one of the openings 8.

It will be readilyseen that owing to the sealing of the mouth of thebottle and the position of the exits it will be impossible for any oneto tamper with the valve mechanism.

Having thus described the invention, what is claimed as new is- 1. Thecombination of a bottle-neck provided with a contracted portion theupper side of which is curved downward to form a concave surface, andalso provided with an annular groove immediately above the contractedportion, said annular groove forming square and approximately horizontalshoulders when the bottle is in an upright position, a valve comprisinga disk having a convex lower surface corresponding to the concavesurface of the contracted portion, the outer edge of said disk having aguide and stopflange projecting therefrom which operates within theannular groove, and a series of lugs projecting upwardly from the guideand stop-flange to engage with the upper side of ders when the bottle isin an upright position, a valve comprising a disk having a convex lowersurface corresponding to the concave surface of the contracted portionand also having a guide-stem pendent therefrom, said disk being providedaround its edge with an outwardly-projecting guide and stop-fiange whichoperates within the annular groove, and a series of lugs projectingupwardly from IO the guide and stop-flange to engage with the seamsupper side of the before-mentioned annular groove and holding the valvespaced there from when the bottle is inverted.

In testimony whereof I aflix my signature in presence of two witnesses.
